uPortal fails with Java 8 version above 255

[cbeach47]

Describe the bug
Running uP-start with versions of Java 8 greater than 255 fails on login with the error. Might be uP core's issue. Will need some investigation.

Caused by: java.lang.IllegalArgumentException: Invalid version number: Version number may be negative or greater than 255
	at com.ibm.icu.util.VersionInfo.getInstance(VersionInfo.java:191)
	at com.ibm.icu.impl.ICUDebug.getInstanceLenient(ICUDebug.java:65)
	at com.ibm.icu.impl.ICUDebug.<clinit>(ICUDebug.java:69)

Note: https://communities.bmc.com/docs/DOC-129065

To Reproduce
Steps to reproduce the behavior:

1. Upgrade Java to 8u265 (I used SDKMan)
2. Start uPortal
3. Access http://localhost:8080/uPortal/Login?userName=admin&password=admin
4. Note error

Expected behavior
It should not fail.

Platform:

• uPortal Version: [uPortal 5.8.2]
• OS: [Ubuntu 16.04]
• Browser [Firefox]

Additional context
Workaround is to downgrade Java8 to something below 255.

This problem come from icu4j dependency used in uPortal here:

uPortal-web/src/main/java/org/apereo/portal/web/view/GoogleHtmlDataTableView.java:import com.ibm.icu.util.ULocale;
uPortal-web/src/main/java/org/apereo/portal/web/view/GoogleCsvDataTableView.java:import com.ibm.icu.util.ULocale;

and seems to be a transient dependency used by com.google.visualization:visualization-datasource

The problem of this lib is there isn't upgrade since 8 years, expect on some forks...

So I would suggest to find an alternative of this lib and to remove it.

In waiting this fork could suit the needs: https://github.com/ci-rt/google-visualization-java

and we have to change the dependency to com.github.ci-rt:visualization-datasource:1.1.3

PS: this issue is a uPortal issue and not a uPortal-start one ;)

Are there any updates on this issue or has it been moved over to uPortal like Julien suggested?

[jgribonvald]

doing the change with the forked lib is not difficult, but doing the test is the difficulty for me as I don't know how to use these views quickly. Is there someone who know ?

Thanks for reporting @cbeach47!
And for tracking down the root cause @jgribonvald!

I've opened two PRs to address this uPortal-Project/uPortal#2157 and #471.
I tested locally with:

openjdk version "1.8.0_265"
OpenJDK Runtime Environment Corretto-8.265.01.1 (build 1.8.0_265-b01)
OpenJDK 64-Bit Server VM Corretto-8.265.01.1 (build 25.265-b01, mixed mode)

@jgribonvald @nickwoodle @cbeach47 if you could take it for a test drive and ensure it works in your environment/preferred JDK, it would be appreciated. 🙇
